Wheels and tyres

[Ambobeer]

Well; it would seem from what I have read so far, that my 94 2nd gen ought to be sat on 15" rims; but it isn't.
I bought it on 16s so someone has already had a play.
Can any one advise me as to whether this is better, worse or just the same? I'm guessing with 16s, potentially there is a slight top speed enhancement and fractionally less pulling power (3 ltr TD, who cares?). I'm also suspecting that the speedo will read wrong but cannot get my head round whether it will read high or low.

I believe I will be needing a set of new tyres next year and I was wondering what other members consider to be the best all rounders. Any advice for specific purposes would also be appreciated.

I'm trying to lump all this together as I may look to putting it back on 15" wheels at the same time. A bit of an holistic approach, I suppose.

You'll probably find that the speedo will be more acurate with 16" wheels.

What tyres size/type do you have at the moment?

What he said

Mine had 16's and 265/70/r16 tyres, it was pretty much on the money for sat nav speedo. changed to 32x11.50r15's and is still pretty much spot on for satnav/speedo calibration.
anything bigger than 32's would lower your speedo speed, but it is said that "standard" wheels and tyres under read the true speed.

It's the tyre circumference that affects speedo readings, not the size of the hole in the middle of it.

Only thing I'd be looking at is the cost of tyres on 16's versus 15's. Sometimes there can be big differences. Work out what size tyre you want in imperial, then compare to the metric version on 16's.

Thats why I asked what tyres are fitted at the moment!

I don't doubt it - my comment was to the op who said -

Woah, woah, woah! My head hurts now.

Obviously the circumference is what matters but surely a 265/70 x 16 has the same size tyre wall as a 265/70 x 15 (185.5mm if my memory serves as to how it's all worked out) so: an increase in central wheel size will increase the overall diameter which will increase the circumference; won't it? Summat to do with the radius and pies if I recall my CSE maths from 30 years ago.

I'm guessing that there are arcane and strange things going on in surf tyre sizes that I do not yet understand (what's all this 30 business? That's a bicycle tyre size)

Anyhow; mine is running 265/70 x 16 Hankook tyres currently.

here you go mate

straight forward solution

bang in the stndard size on one side and the other size on the other

http://www.miata.net/garage/tirecalc.html

very useful

pretty much A 265/70 ON A 16 GIVES SAME SIZE AS A 31/10 ON A 15

About 1.5" on rolling diameter bigger

that website will show you the basic sizes and how far out the speedo maybe

hope it helps

and if interested, i migth have a set of std alloys with std tyres for sale cheaply

Yes if you compare a 265/70 x 16 to a 265/70 x 15 the 16" version will be bigger. Didn't know you were asking about specific tyre sizes so answered on what info you gave.

The '30 business' is afaik imperial or American sizes, which give the tyre diameter in inches, followed by its width in inches, followed by the size wheel it fits on in inches. 30x10.5x15 as an example.

Please explain to me how a 265 tyre is bigger if you cut a 16" hole in it instead of a 15" hole lolololololololol

Sh*t! Is that how they make tyres? One big disc of rubber and then they cut a hole in it?
God Damn, you learn something new everyday

the 265 part is just the width..

the / something is a percentage of the width that makes the sidewall

so a 265/70 no matter what size diameter will in theory have the identical width and sidewall size

obviously if you put the identical sidewalls onto different size rims then the overall diameter becomes bigger..

so a 265/70 on a 15 will have
Width - 265mm
Sidewall - 185 mm
Radius - 376 mm
dia 752mm

on a 16 it will have
Width - 265mm
Sidewall - 185 mm (same as its a percantage)
Radius - 388 mm
dia 777mm

so when travelling at 60 mph the 15" would read correct and the 16 would still read 60, but you'd be travelling 62 mph

use the tyre calculator i posted up earlier if that doesnt make sense

but i hope that answrs your question

[Ambobeer]

what ya think of these tyres

I think they're black and round and have sqiggles on them.

I also think they would look rather good on mine, what are they? More to the point, are they any good for all round use (judging by the snorkle I'd say I do a teensy weensy bit less off roading than you) and are they reasonably priced?

[JUDWAK]

they are a little slippy on wet roads other than that they are a good tyre
my truck is off the road its in for a lexurf in april and iam going to have bigger tyres
so i dont need them tyres they are on 15 rims and i have no lift that the biggest tyre you can get on a 2nd gen with out lifting it
i only need any sort of wheel and tyre on it so it can be moved when i need to

but they are just sat there iam up for a swap maybe
if they are your sort of thing
they are very agresive tyre full muds
they give off a little road noise
but go anywere brill in the snow
up to you
